1981 Kawasaki GPz550

When Kawasaki unveiled the 1981 Kawasaki GPz550 in 1981, it signaled the company's commitment to the sport bike segment. Built in Japan, this sport bike embodied the spirit of 1980s motorcycling.

The 1981 Kawasaki GPz550 is motivated by a 553cc DOHC inline-4 four-cylinder unit delivering 58hp at 9500 rpm. Breathing through 4x Mikuni carburetors and kept cool by air-cooled, the engine drives through a 6-speed transmission with chain final drive.

Built around a steel double cradle frame, the 1981 Kawasaki GPz550 suspends its 194 kg (428 lbs) on air-assisted fork forks and uni-trak monoshock rear units. Braking relies on dual disc at the front and single disc at the rear, with a 1430 mm wheelbase providing stability.

Performance-wise, the 1981 Kawasaki GPz550 achieves a claimed top speed of 185 km/h (115 mph). With a generous fuel capacity of 16.0 liters, it offers reasonable range for sport bike duties. The seat height of 800 mm makes it comfortable for most riders.
